摘要
目的:探究干品糙海参的营养成分。方法:考察了糙海参的蛋白质、脂肪、水分、灰分以及氨基酸含量的差异,并研究了糙海参多糖的分子量和组成。结果:干品糙海参含有较多的蛋白质,其次是水分。氨基酸的总百分含量为60.45%,其中鲜味氨基酸占47.19%,抗氧化氨基酸含量6.94%,羟脯氨酸6.31%。糙海参多糖重均分子量(Mw)是68592u,并含有较多的羟基、氨基、羧基、硫酸酯,均为硫酸软骨素E。结论:糙海参具有很高的营养价值。
Objective： To study the nutrient contents of dry Holothuria scabra Jaeger. Methods： we investigate the difference about its protein, fat, water, ash and amino acid, we also research its molecular weight and composition. The result is dry Holothuria scabra Jaeger contains more protein, the next is water. The total percentage content of amino acids is 60.45%. The proportion of prawn flavor amino acid is 47.19%, amino acids of oxidation resistance is 6.94%, hydroxyproline is 6.31%. Holothuria scabra Jaeger mucopolysaccharide, s Mw is 68592 u, it also contains more hydroxide radical, amino, carboxyl and sulfuric acid ester, they are also chondroitin sulfate E. Conclusion： Holothuria scabra Jaeger have high nutritional value.
